of Newark, county of Essex, and State of New Jersey, have inventedcertain new and useful Improvements in Slot-Closing Devices forCoin-Controlled Machines, of

which the following is a specification. I

This invention relates to an improved de vice for closing slots inmachines that are actuated by coins or checks, and principally inmachines for vending articles. v

In order to prevent the insertion of coins after the supply of articlmis exhausted, de

vices are in use that close the slot, and this' c invention is animprovement in this l1ne of device, being positive in its action, simplein construction and be ng protected agalnst premature opcratlon, that isthe last of the articles to be vended or dispensed must bev ejected fromthe goods-chute before the device operates. The device also embodies animproved device for insuring the feeding of all the ait icles. since afollower that operates the trip' for the closing device is weightedsuiiiciently so as to keep the articles that are to be fed from thebottom of the chute in contact and to also insure their gravitation sothat they do not stick in the chute.

The device is illustrated as used in con'- A junction with a goods-chutesuch as 1s'de-' scribed and illustrated in my application for LettersPatent tiled December 6, 1915, Serial No. 65,190,0t which thisapplication is a division.

The inventionis illustrated in the accoin panying drawing, in whichFigure 1 is a front view or a goods chute equipped with my slot closingdevice. i Fig.

2 is a side view oi? the chute shown in Fig. 1, and also having a partoi the casing shown in section. Fig. .3 is 'a'perspective view of theplate that is utilized to close the slot, and Fig. i is a perspective ofthe follower that rests on the goods and which actuates the trippingmechanism to release the plate which closes the slot.

in the drawing the form of goods-chute 10 is similar to the oneillustrated in the application mentioned hereinbeio're, and has itsfront wall It]. cut away as at 12, leaving side-strips 13 so that theopen space 12 can plate 30. The plate 30 is cut away as at 32, the sideplacing of the'packages in the chute, the

packages resting on an ejecting and supportmg plate 15 extending forwardfrom a lever 16 which'is operated by any desired .form of mechanism,such mechanism not being shown in the" drawing. The ejecting plate 151sused to expel the packages one at a time so that they pass out, whenexpelled, onto the tray 17 and out through a suitable delivery opening18 in the casing 19. The i 'r'ont wall of the casing 19 has a coin slot20 in itthrough which the coins are inserted and .from which theyareconducted to any suitable operating mechanism. The side 'strips'13 ofthe chute are connected at the bottom by a transfer strip 21 into whichis screwed a. screw 22 or other suitable pivot for the l0w'er1arm 23 ofthe right-angled lever 24, this loweror horizontal arm hav-. ing anextension .25 which preferably eX- tends slightly into the space betweenthe side strips 13-. The upright arm 26 of the right-angled lever 24: isprovided with a pin The. pin 27 normally rests in a hole 28 in theflange 29 of the closing plate 30. The closing plate 30 extends acrossthe front of the goods-chute and is adapted .to swing in a pivot 31, theform shown being a screw which is not screwed in untilit binds butallows space for the free swinging of the walls of the cut-away part orslot 32 being preferably beveled as at.83 s0-as to facilitate theinstallation of the plate 30, since it is desirable to remove this plate30 to make it easier to put the packages 14: into the chute. .The plate30 thus being pivoted or supported at one end so that it can swing onthis end, drops by gravity when it is released. lit is,- however, heldagainst swinging by reason of the pin 27 resting in the hole 28 andacting to hold the plate in the position shown in full lines. in Fig. 1.On

the stack of packages 14: is ajfollower 34E which is of material weightand is preferahly provided with upright flanges 35 and 36,- these notbeing essential but they are desirable because they prevent unduetilting of the follower and insure its travel directly down inside thechute. The follower is provided with a lip 37 which extends forward andis over the end or eXten-' 'sion of the lever 24. The height of the lip37 above the bottom of the follower 34 is such that after the lastpackage is ex pelled and-'the follower drops to take its 7 chine.

- plate sticking, and since the weight is all place, the. lip engagesthe extension 25 and forcesit down. When this end 25.is

forced down it swings the end carrying the pin 27 inward, which releasesthe plate 30 and the plate 30 swings to the position shown in dottedlines in Fig. 1, and when so swung it covers the coin slot 20. so thatno more coins can be inserted into the ma- The beveled or thinned part33 underneath the head of the screw 31 provides a narrow edge on whichthe plate swings so that there is very little likelihood,of the to oneside of the pivot, the plate swings quickly into its closing position. v

The device takes up but little room in the machine, being confined forthe most part within the lines of the chute, and it is easily andquickly set into its normal position.

Having thus described my invention, I claim: p 7

1. A slot closing device comprising a goods-chute adapted to holdarticlesto be ejected from the bottom thereof a plate swinging on .thegoods'chute, tripping means for supporting the plate in its inoperativev position, and a follower resting on ,the articles in the chute andadapted to actuate the tripping means and to withdraw the supportfromthe plate when the last article is expelled from the chute, the partsbeing so disposed that when its support is with; drawn the plate swingsin front of a slot in the machine.

A slot closing device comprising a goods-chute, the goods-chute beingadapted to support articles ejected from the bottom thereof, aright-angled lever mounted on the chute, a pivot for the leverintermediate of the ends of one of its arms, a plate adapted to besupported and tripped by said rightangled lever, and a follower on thegoods in the chute and adapted to trip the lever as the last article isexpelled from the chute. and to thereby withdraw the support from I theplate.

31A slot closing device comprising a,

' goods-chute having an opening down'the goods ejected from the bottomthereof, a

4. A slot closing device comprising a goods-chute/adapted to containarticles dis pensed from the bottom thereof, the chute having avertically arranged opening, a follower on the goods, a lip on thefollower extending through the opening in the chute. a right-angledlever having a horizontal arm and anupright arm, the horizontal armbeing pivoted intermediate of its length, a plate pivoted at one end tothe chute, and coacting means on the upright arm and on the plate forsupporting the plate in an inoperative position against the action ofgravity, the lip of the follower being adapt ed to engage the horizontalarm of the lever to withdraw the support from the plate.

5. A slot closing device comprising a goods-chute adapted to containarticles e ected from the bottom of the chute, the chute having avertically arranged opening, a follower on the goods with a lipprojecting through said opening, a right-angled lever with a horizontalarm and an'upright arm.

the horizontal arm being. pivoted with its end in the path of the lip onthe follower.

a pin on the upright arm, and a closing plate pivoted near one end andhaving a flange on its other end, the flange having an opening toreceive the pin of the upright arm and to normally support the plateagainst the action of gravity.

6. In a slot closing device, a closing plate having an inclined slotnear one end, the slot having beveled edges, the free end of the platehaving a flange thereon, the flange having an opening therein, a leverhaving a pin to enter the opening of the plate, a

goods-chute adapted to contain articles eject ed from the, bottomthereof, a follower on the articles in the chute, and means operated bythe follower for withdrawing the pin from the opening in the plate,thereby permitting the plate to turn by gravity.

In testimony that I claim the foregoing. I hereto set my hand, this 2ndday of May. 1916.
